But they make for poor laboratory subjects. Some require prescriptions. If the limb is amputated at the shoulder or hip, the blastema creates the full leg. One of the genes molecular targets, for example, is a microRNA (a small noncoding RNA molecule) called let7, which in turn regulates hundreds of other genes, so the effects of Lin28a can set off a complex array of regulatory interactions.
